There's two grey "bolt looking" screws on the backside of your headlight. The "washers" on them have teeth, this is for a big Phillips head screwdriver. Put the screwdriver behind it and twist. The top one is up and down. Bottom toward your fender is left to right. It's easy to do

i dunno bout you but my bottom screw goes up and down and top goes left and right.

Confirmed, it's the screwdriver direction. Turn screwdriver CCW to move beams down and CW to move beams up.
Now I am confused on the final turn after adjusting. Is it screwdriver or screw turned CW on final turn???
